The topic should be small, and the topic of the paper should be as big as possible. For beginners, it should be from easy to deep and from easy to difficult. Because the topic is relatively small, it is easier to master. But don't think that if the topic is small, the paper will have no weight. In fact, the weight is not necessarily proportional to the size of the topic.

The topic should be simple, concise and straightforward, and the number of words should be controlled within 20 words. A concise summary of the article is a successful topic.

The topic should be new and the title should be novel and eye-catching. The first thing that attracts readers' attention is always its title. When people browse a paper, they first judge whether it is necessary to read it from its title. What is new here is not novelty, but refers to new angles, new contents, new situations and new discoveries.

The topic should focus on the proposition with huge content, and the linkage proposition cannot be used, because it means that the thesis has two centers, which is the taboo of graduation thesis.
